[rhos-list] Nova-network v.s. Quantum in Openstack preview

Fri Feb 15 15:06:52 UTC 2013

Hi, Perry:

Thanks a lot for chiming in! KVM crashed during operation. VM stayed in "starting" mode for about 10 secs and then went straight to "paused" mode.

Here is the output you are looking for and appreciate the head up of RHEL 6.4 GA release! I cannot wait!

Hi, Gary:

I tried to put SELinux in PERMISSIVE mode and spawned up new VM using
cirros image today, but still no luck. I spent the rest of the day
searching Redhat bugs based on numerous error msgs in various log
files. Found tons of stuff, but most of them didn't seem to be
relevant and helpful.

One thing caught my eyes is a case submitted back in 2010 and updated
early this year. The KVM error message in instance console log is
similar to the one in my case. Based on the description, seems like
the KVM crash is caused by defective CPU or unsupported CPU model. I
will try different machine for better luck.

Shixiong,

Is it a kvm crash during operation or does it fail to start at all?

Just as a sanity check, can you run virsh capabilities and give us the
output?

And also:
lsmod | grep kvm

Will keep you posted if I can root cause the problem. In the
meanwhile, if anything pops to your mind, please let me know.

Thanks for the update. Which RHEL version are you using? I am using RHEL
6.4. I do the following:
- install from disk
- subscripion registration
- i then make sure that the RHEL 6.4 beta repo is added:

[rhel64beta]
name=RHEL64 BETA
#baseurl=http://download.eng.tlv.redhat.com/pub/rhel/rel-eng/RHEL6.4-20130130.0/6.4/source
baseurl=http://download.eng.tlv.redhat.com/pub/rhel/rel-eng/RHEL6.4-20130130.0/6.4/Server/x86_64/os/
enabled=1
gpgcheck=0
(please do not do a yum update after this - it causes conflicts with packstack)
- then i install the latest packstack
- run packstack and everything works (bar the minor iptable issue we have discussed)

One hiccup in the above...

Because the RHEL 6.4 GA release is imminent, the RHEL 6.4 Beta Repos
have been emptied.  It's part of the normal release engineering process.
So for a short time, you might be stuck with getting updated packages
or reinstalling from scratch on a new host.

This issue should clear up in the next week as we get GA packages out
the door.  I'll send a more general note to the list about it.

Perry
